Petroleum, natural gas, and coal continue to dominate U.S. energy consumption
Petroleum, natural gas, and coal continue to dominate U.S. energy consumption Fossil fuels—petroleum, natural gas, and coal—have accounted for at least 80% of energy consumption in the United States for well over a century. Overall energy consumption in the United States reached a record high in 2018 at 101 quadrillion British thermal units (Btu), of which more than 81 quadrillion Btu were from fossil fuels. Despite the increase, the fossil fuel share of total U.S. energy consumption in 2018 increased only slightly from 2017 and was the second-lowest share since 1902.
